Unspecified superficial injury of lip, initial encounter

This code signifies a non-specific, minor injury to the lip, such as a contusion, abrasion, or blister, where the exact nature of the superficial trauma is not documented. It indicates that the injury affects only the outermost layers of the lip tissue.

Apply this code when documentation specifies a superficial lip injury but lacks further detail regarding the type of injury (e.g., "lip injury," "trauma to lip"). This is appropriate for the initial visit for treatment of the injury.

• Ensure documentation explicitly states "unspecified" or lacks specific detail for the superficial injury type.
• Do not use if a more specific superficial injury (e.g., S00.511A for abrasion) is documented.
• Remember the "A" seventh character for initial encounter; subsequent care will require different seventh characters.
